Title: Improvements in or relating to calenders and the like
IPC: B29C43/22
Filed: 1952-01-04
Abstract: 722,531. Adjusting bearings. FARREL-BIRMINGHAM CO., Inc. Jan. 4, 1952 [Jan. 4, 1951], No. 326/52. Class 12 (1). [Also in Groups V and XXII]. A calendar or like apparatus, e.g. for rolling very thin films of plastic material, comprises a pair of co-operating rolls mounted for relative approaching and separating movements, a fluid-pressure cylinder and piston for applying pressure to one of the rolls to urge it towards the other, and a screw which acts on the piston and is adjustable to vary the pressure applied by the cylinder and piston to the said one roll, this screw being connected to the cylinder to effect movement of the cylinder to move the said one roll away from the other. The drawings show the invention applied to one roll 14 of a machine including four rolls 11, 12, 13, 14, the roll 14 being movable to and from roll 13. The reduced ends 18 of roll 14 are each mounted in a journal 19 secured by bolts 24 to a hydraulic cylinder 28. The cylinder-journal assembly 28-19 is moved as a unit by rotation of a screw 31 threaded into a standard 16 at 32. Within the cylinder is slidably disposed a cup-shaped piston 40, the pressure fluid space being shown at 42. The screw 31 passes loosely through the head 29 of the cylinder and its end bears against the piston at 45. 'A retracting nut 46 is threaded on the end of the screw inside the cylinder. The pressure in the space 42 is the calendering pressure. When the roll 14 is to be withdrawn from roll 13 the screw is rotated to pull nut 46 against the inside of cylinder head 29. To adjust the axis of roll 14 to make a slight angle to the axis of roll 13 (to compensate for the bowing of the central portion of the rolls under pressure) each end of roll 14 is moved vertically by means of an adjusting screw 48 which moves a nut 21 carrying a wear plate 20 which supports journal 19. When the journal 19 thus moves vertically it moves relative to cylinder 28, the bolts 24 moving in elongated slots and a wear plate 35 secured to the journal rolling on ball bearings 38 in a disc 37 disposed between plate 35 and a similar plate 36 on the cylinder; the disc is carried by plates 56 pivotally supported on the cylinder and journal at 59 and 60. When screw 48 is backed off, a fluid pressure piston 50 pushes the journal down again. Pressure is applied to the fluid, e.g. oil in spaces 42 by means of air-pressure pistons Fig. 7 (not shown).

Hand driving-mechanism. - A manumotive vehicle having a body in the form of a boat and of the kind wherein independent hand-lever driving-mechanism is provided on each side of the vehicle so that steering can be effected by varying the stroke of one lever relatively to the other, is characterized by the provision of a brake in association with each lever in such manner that when the lever is moved beyond a predetermined point in one direction about its pivot the brake is applied. The vehicle may be fitted with wheels with or without self-laying tracks, or with paddles, screw propellers, &c. The hand-levers 4, connected by horizontal pivots 7 to parts pivoted vertically to brackets 3, actuate spring-returned cords and chains 8, 10 driving the wheels 16 by one-way clutches. To apply a brake the corresponding hand-lever is pressed forward until an arm 27 on the verticaliy-pivoted part engages with a lever connected to a flexible brake-actuating member 24 passing around pulleys 26, 26a, 26<b> to the vertical arm 20 of the spring-fitted brake lever 18. A castor 28 may be provided and this may be connected to steering means such as a tiller. The Provisional Specification refers (1) to a link connecting the hand-lever to a further lever which is attached to the flexible driving-member, and (2) to a friction driving-wheel for bearing upon the road wheel or a friction disc thereon, the brake shoe being arranged to engage with the road wheel or the friction disc.

Title: A method of producing sponge iron
IPC: C21B13/08
Filed: 1964-01-06
Abstract: In a method of producing a product of sponge iron character containing at least 90% metallic iron, wherein green pellets having diameters between 5 and 25 mm., and consisting of oxidic iron ores, are reduced in a bed of solid carbonaceous reducing agent in a rotary furnace with hot gases passed in countercurrent to the direction of travel of the pellets through the furnace, the solid carbonaceous reducing agent is present in an amount 150-200% in excess of that amount calculated to be required for the reduction, and has a grain size diameter which does not exceed 50% of the smallest grain size diameter of the pellets or iron ore present.  The resulting reduced iron is in the form of pellets of substantially the size of the initial pellets and fine grains caused by abrasion and having a maximum diameter of 2 mm.  The iron pellets are separated from the remainder of the furnace discharge by screening at a temperature between 700  DEG C. and 900  DEG C.  The hot pellets thus separated out may be directly charged into a melting furnace, or immediately submitted to hot briquetting. The pellets may consist of a mixture of different ores, e.g. a mixture of acid and basic ores such that a self-fluxing slag is produced, or a mixture of ores of unsatisfactory binding properties and good binding properties may be used.
